They were sparse until late 80s when ITV got the contract, then they seemed to show one a week but were not allowed to show any until a month or so into the season. The later 80s ones were all Sunday bar Liverpool v Arsenal the 1989 title game from what I remember.
City were on in the late 80s on Sunday in Div 2, the game v Villa in 87/88 when Morley got sent off for an elbow. Pretty sure that was ITV, also sure we had a very poor record of games live on TV only the Villa win. Even when on Sky we took ages to win one. Can't remember any until Ipswich when Lomas scored in 1997.
